Description

{A self-audit and management system for bridge based on IoT using intelligent remote terminal device}

The present invention relates to an IoT-based bridge autonomous inspection and operation management system using an intelligent remote terminal device, and more particularly, by installing an intelligent remote terminal device (RTU) 200 for each bridge, the bridge detection means 100 Using the transmitted detection information and image information for each detection factor, it is determined whether the situation in the bridge is a bridge traffic accident, a bridge structure related situation, or a bridge environment related situation, and the bridge situation response means 300 is used according to the situation. After operating and taking autonomous action for each situation, autonomous action event information for each situation including the unique identification information of the intelligent remote terminal device is generated and transmitted to the intelligent central platform server 400, and the operation status of the objects to be inspected is autonomously checked. , By generating failure information for each inspection object according to the inspection result and providing it to the intelligent central platform server 400 through the IoT communication network, it is easy to take autonomous measures for bridge accidents and monitor autonomous inspection of various facilities installed in the bridge. Thus, it relates to an IoT-based autonomous inspection and operation management system for bridges using intelligent remote terminal devices that enable preliminary inspection of facilities before a bridge accident and quick initial response in case of a bridge accident.

Today, as the area of activity of people gradually expands, bridges are installed to shorten the travel time between regions.

Bridges located in places where there is a lot of vehicle movement pass by hundreds or thousands of vehicles a day, and the weight of large vehicles can cause the bridge to crack and tilt, and the bridge may be cracked and tilted even by frequent earthquakes. Can

In some cases, the structural change of the bridge can lead to a major accident. Accordingly, conventionally, the manager (operator) who manages the safety condition of the bridge visually inspects the various places of the bridge at regular intervals, or the operator directly enters the water and inspects the lower part of the submerged pier to check the safety condition. Manage.

However, the management methods of the bridge as described above cannot be monitored in real time because the manager (operator) visually checks the condition of the bridge at regular intervals, and the manager (operator) is responsible for checking the bridge. The downside is that you have to go directly to the area.

As a countermeasure against this, in "Bridge/Tunnel Safety Status Management System and Method using Wireless Short-range Communication" (Korean Patent Publication No.: 10-2007-0043491), a plurality of wireless short-range sensor modules are attached to the bridge/tunnel, and a plurality of wireless short-range sensor modules are attached. A technology that manages the safety state of the bridge/tunnel is disclosed by receiving bridge/tunnel information collected and transmitted by hopping method between short-range sensor modules in real time and analyzing it.

However, the above-described method has a problem in that when a problem occurs in a sensor, a pre-inspection or post-management according to the inspection is not performed, so that when a sensor error occurs, an appropriate initial response cannot be performed.

And, in recent years, as artificial intelligence emerges and objects become intelligent in the era of the 4th industrial revolution, objects are becoming unmanned and autonomous beyond automation as objects think and decide on their own such as collecting, comparing, analyzing, judging, and taking measures.

The existing bridge management and operation system in the era of the 3rd industrial revolution measures, collects, and transmits the status of safety facilities within the bridge, and the manager compares, analyzes, and judges and remotely controls the accident response and operation efficiency.

In particular, there is a limitation in controlling remotely by the administrator in case of communication loss or problems such as facilities for safety of bridges and measuring instruments.

On the other hand, many measurement sensors are installed at the bridge site for bridge safety management.However, in the case of the currently applied system, the fault diagnosis function of its own system is applied, but it is necessary to determine the presence or absence of a failure by grasping the operation status of the connected facility, the measurement sensors. In spite of the failure of the measurement sensor due to the lack of introduction of technology, it is not possible to promptly respond to a bridge accident due to malfunction or incorrect judgment because the appropriate response cannot be performed immediately, and thus the situation is always exposed to disasters.

Therefore, in the current operating system, there are many malfunctions of facilities due to frequent errors of measured data values, and civil complaints have been generated, and use is avoided.

In addition, the government and local governments have recently established and operated an integrated control room in the government building to integrate and manage facilities scattered within the jurisdiction (water supply facilities, disaster preparedness facilities, environmental management facilities, road facilities, bridge facilities, etc.). .

In order to operate facilities in these various fields in one integrated control room, a person in charge of each field must reside, monitor 24 hours a day, 365 days a year, find problems, and take action.

The HMI program of the integrated management room currently in operation receives various data and displays it on the operation screen, and the manager is operating in the form of viewing, comparing, analyzing, judging, and remote control of the measurement screen. Therefore, many operating personnel are deployed in each field in the integrated control room to monitor facilities 24 hours a day and night.

In the case of local governments, the person in charge of the relevant department performs a number of tasks. However, when monitoring by residing in the integrated control room, difficulties arise that cannot see other tasks.

In addition, it takes from several minutes to tens of minutes to find data stored in the database, and frequent data loss due to communication loss occurs.

Therefore, an intelligent remote terminal device (RTU) equipped with a bridge-related operating system (OS) autonomously checks through the collected data to detect errors, and when communication is lost, the data is self-saved and the data is automatically restored to resume communication. Develop technology that enables seamless transmission of high-quality data as possible and compares, analyzes, and judges the data collected from the field with the management manual, informs the manager of the necessary information, stores it separately in the database, and informs the connected remote terminal device of the situation The time has come for the autonomous inspection of bridges installed in the integrated control room to respond and take action and development of autonomous operating platform technology.

Since the conventional technology automatically operates the bridge accident countermeasure facility when an abnormality occurs in the facility within the bridge, civil complaints according to the malfunction occur, and the current bridge structure disaster prevention systems are almost useless, which is useless.

In the following, features of the intelligent remote terminal device 200 will be described in detail with reference to FIGS. 2 to 3.

The intelligent remote terminal device 200 includes a bridge situation response means autonomous inspection unit 210, a bridge detection means autonomous inspection unit 220, an RTU autonomous inspection unit 230, a central control unit 240, an autonomous action unit 250 ), and an IoT wireless communication unit 260.

Specifically,

The bridge situation response means self-checking unit 210 transmits a self-check signal to the bridge situation response means 300 periodically according to preset autonomous inspection schedule information in order to autonomously check the operation state of the bridge situation response means 300. Transmit and obtain a response signal to the autonomous inspection signal from the bridge situation response means 300, it is determined to be normal, and the unique identification information of the bridge situation response means 300 that did not obtain the response signal is extracted, and the extracted unique identification It generates failure information for each bridge situation response means including information, and performs a function of transmitting the generated failure information for each bridge situation response means to the intelligent central platform server 400 through the IoT wireless communication unit 260.

In other words, after transmitting the autonomous inspection signal to the bridge situation response means 300 periodically in a normal time, when acquiring the response signal to the autonomous inspection signal from each of the bridge situation response means, it is determined as normal. However, if the response signal cannot be obtained, failure information for the corresponding bridge situation response means is generated.

For example, if a self-check signal is transmitted to the blocking layer and a response signal cannot be obtained, the IoT wireless communication unit 260 extracts unique identification information of the blocking layer, and then generates blocking layer failure information including the unique identification information of the blocking layer. ) To be transmitted to the intelligent central platform server 400.

The bridge detection means self-checking unit 220 receives detection value information from the bridge detection means 100 periodically in order to autonomously check the operation state of the bridge detection means 100, and uses the received detection value information. After determining whether the bridge detecting means 100 has a failure, extracting the unique identification information of the bridge detecting means 100 determined to be a failure, and generating failure information for each bridge detecting means including the extracted unique identification information, The fault information for each bridge detection means is transmitted to the intelligent central platform server 400 through the IoT wireless communication unit 260.

In order to perform the functions as described above, the bridge detection means self-checking unit 220,

A sensing value receiving module 221 for receiving an analog current sensing value, an analog voltage sensing value, or an analog resistance value from each of the sensors constituting the bridge sensing means 100,

A digital conversion module 222 for converting the received analog detection value into a digital value,

A failure determination module 223 for determining whether each sensor constituting the bridge detection means 100 has failed by using the change characteristic of the converted digital value,

After extracting unique identification information of each sensor constituting the bridge detection means 100 determined as a failure, generating failure information for each bridge detection means including the extracted unique identification information, the generated failure information for each bridge detection means is It includes a bridge detection means failure information generation module 224 to be transmitted to the intelligent central platform server 400 through the IoT wireless communication unit 260.

Specifically, the sensing value receiving module 221 receives an analog current sensing value, an analog voltage sensing value, or an analog resistance value from each sensor constituting the bridge sensing means 100, and digitally converts the received analog sensing value. It is provided to the conversion module 222 to convert the received analog detection value into a digital value. At this time, the normal range of the analog detection value received by the detection value receiving module 221 is current (4mA ~ 20mA) or voltage (1v ~ 5v) or (0.1MΩ 0.5MΩ), and the digital conversion module 222 is It is characterized in that the normal range of the converted digital value is (13107 ~ 65535).

For example, the bridge detection means providing an analog detection value is of different types, such as wind speed detection sensor, freezing detection sensor, water level detection sensor, visible distance detection sensor, motor detection sensor, earthquake detection sensor, etc. The analog current detection value provided by the means is in the range (4mA ~ 20mA), and the analog voltage detection value is in the range (1v ~ 5v). In addition, a digital value obtained by converting the analog detection value to a digital value is in the range (13107 ~ 65535).

That is, the digital conversion module 222 converts the analog current detection value 4mA or the analog voltage detection value 1v to a digital value of 13107, and converts the analog current detection value 20mA or the analog voltage detection value 5v to a digital value of 65535. Of course, an analog current detection value between (4mA ~ 20mA) or an analog voltage detection value between (1v ~ 5v) or (0.1MΩ 0.5MΩ) is converted to a digital value between (13107 ~ 65535).

The failure determination module 223 does not have the converted digital value, the converted digital value is fixed, the converted digital value is fluctuating out of the normal range (13107 ~ 65535), or the converted digital value is If it is fluctuating only in two digital values, it is judged as a failure.

For example, if the converted digital value does not exist, this means that the analog detection value is not detected, and this can be determined as a failure.

And, whether the digital value is in the normal range or out of the normal range, if it does not move and is a constant fixed value, it is judged as a failure. For example, digital values vary slightly from moment to moment, but they must be fluctuating to be normal, while digital values that do not change are judged to be abnormal.

And, if the digital value fluctuates outside the normal range (13107 ~ 65535), it is determined as a failure. For example, a normal digital value should fluctuate within the range (13107 ~ 65535), but if it fluctuates within the range (66545 ~ 67777), which is a digital value outside the normal range, it is judged as a failure.

In addition, if the converted digital value is fluctuating only in two digital values (referred to as a hunting phenomenon), it is also judged as a failure. For example, if the converted digital value of the earthquake detection sensor goes back and forth between 14100 and 59000 values ^{, it detects 1 m/s 2} , detects 9 m/s ^2, and detects 1 m/s ^{2 again.} Then, it detects 9 m/s ^2, and it is judged as a failure because such detection cannot be found in common sense.

The variation of the digital value described above will be described in detail.

The types of bridge detection means 100 are different, but if it is normal, the analog current detection value must fluctuate slightly every moment within the range of 4mA to 20mA, so the converted digital value must also fluctuate every moment within the range of (13107 to 65535).

For example, when an earthquake detection sensor capable of detecting vibrations of ^{1 m/s 2} to 10 m/s ^{2 detects 1 m/s 2} vibration, the digital value fluctuates from time to time near the lowest digital value of 13107 (13107, 13110, 13108, 13109...) should be normal, and when 10 m/s ² vibration is detected, the digital value should fluctuate (65535, 65530, 65527, 65529...) from time to time around the highest digital value of 65535.

That is, if the bridge detection means 100 of different types of detection targets are normal, the digital values converted from the detection values to digital must all change slightly every moment within the range (13107 ~ 65535) to be normal.

The bridge detection means failure information generation module 224 extracts unique identification information of each sensor constituting the bridge detection means 100 determined as a failure, and generates failure information for each bridge detection means including the extracted unique identification information After that, the generated fault information for each bridge detection means is transmitted to the intelligent central platform server 400 through the IoT wireless communication unit 260.

The RTU self-checking unit 230 transmits the RTU self-checking signal to the central control unit 240 periodically according to preset RTU self-checking schedule information in order to self-check the operation state of the intelligent remote terminal device itself. If the response signal of the central control unit 240 is obtained for the inspection signal, it is determined as normal, and if the response signal is not obtained, the unique identification information of the intelligent remote terminal device is extracted, and RTU failure information including the extracted unique identification information is generated. And, it performs a function of transmitting the generated RTU fault information to the intelligent central platform server 400 through the IoT wireless communication unit 260.

For example, an RTU self-check signal of'AUTO_REQUEST#ID:1-RTU#POWER#2020-02-20-09:01' is generated and transmitted to the central control unit 240, and the response signal'ID: If a signal of 1-RTU#POWER#OK#2020-10-10-09:01' is acquired from the central control unit 240, it is determined to be normal, but if the response signal to the self-check signal cannot be obtained, Generates RTU failure information of'ID:1-RTU#POWER-ERROR#2020-10-10-09:01' including'ID:1-RTU', which is unique identification information, and the generated RTU failure information is It is to be transmitted to the intelligent central platform server 400 through the Internet wireless communication unit 260.

The central control unit 240 controls the operation of each component constituting the intelligent remote terminal device, and upon receiving the RTU self-check signal, checks the operation state of each component constituting the intelligent remote terminal device, and the inspection result If all the components are normal, a response signal is provided to the RTU self-checking unit 230, and if any of the components are abnormal, a function of not providing a response signal to the RTU self-checking unit 230 is performed.

For example, when receiving the RTU self-check signal'AUTO_REQUEST#ID:1-RTU#POWER#2020-10-10-09:01' to check the operation status of the power supply from the RTU self-checking unit 230 , Check the operation status of the power supply, which is a component of the intelligent remote terminal device, and if there is no abnormality as a result of the inspection, a response signal for the RTU self-check signal is provided to the RTU self-checking unit 230, and if there is an abnormality, a response signal is provided. It is not provided to the RTU self-checking unit 230.

In the above example, the operation check is performed on the power supply, which is a component of the intelligent remote terminal device, but it checks the operation of all components of the intelligent remote terminal device, and responds if there is any problem. The signal is not provided to the RTU self-checking unit 230.

In particular, when the central control unit 240 does not provide a response signal to the RTU self-checking unit 230 (operation check result of all components constituting the intelligent remote terminal device, if at least one is abnormal), an abnormal person Provides information on the component.

In this case, the RTU self-checking unit 230 is characterized in that when receiving information on an abnormal component instead of a response signal from the central control unit 240, the information on the abnormal component is included in the RTU failure information.

In the present invention, by configuring the RTU self-checking unit 230 and the central control unit 240 as described above, even a failure of the intelligent remote terminal device 200 itself can be accurately analyzed.

That is, the RTU self-checking unit 230 generates failure information when it fails to obtain a response signal from the central control unit 240, and generates failure information even when obtaining information on an abnormal component instead of the response signal. It is to include information about abnormal components in the.

On the other hand, the intelligent remote terminal device (RTU) 200 of the present invention may further include a communication loss data automatic recovery unit 270.

The communication loss data automatic recovery unit 270, as shown in Figure 3,

The response request signal is sent to the IP address of the intelligent central platform server 400 to check whether a response signal is received, but if the response signal is not received, it is determined as a communication error and counts as many as a predetermined number of times, and the response signal continues afterwards. Connection communication monitoring module (271) for sending a reset command signal to the communication power reset command module if it is not received:

Communication power reset command module 272 for resetting the power of the IoT wireless communication unit 260:

The response signal check module 273 after reset to check whether the response signal is received by retransmitting the response request signal to the IP address of the intelligent central platform server upon reset:

If the response signal is not received even if the response signal is checked again by the response signal check module after the reset, the response signal is determined as a communication failure, and continuous operation command information to continuously perform self-check according to the set scenario after the time of the communication failure. Sustained operation command signal transmission module 274 for transmitting to the means self-checking unit 210, accident detection means self-checking unit 220, RTU self-checking unit 230:

And a continuous operation result information transmission module 278 for transmitting the autonomous inspection result information stored in the continuous operation result storage module to the intelligent central platform server when receiving an answer signal from the intelligent central platform server. do.

Specifically, the connection communication monitoring module 271 transmits a response request signal to the IP address of the intelligent central platform server 400 and checks whether a response signal is received. If it counts as many times as the specified number of counts and does not receive an answer signal continuously after that, it performs a function to send a reset command signal to the communication power reset command module.

For example, it sends its own IP address to the DDNS server located in the central management office according to the set time, and the DDNS server determines the normal communication state when it gives an ACK signal to the access communication monitoring module.

However, when there is a communication failure, the connection communication monitoring module cannot receive an ACK signal even if it sends an IP address to the DDNS server, so it determines this case as a communication error state.

If it is judged as a communication error state, if it is set for 5 seconds, for example, as many as a predetermined number of counts, a reset command signal is sent to the communication power reset command module if the response signal is not received within 5 seconds.

At this time, the communication power reset command module 272 resets the power of the IoT wireless communication unit 260.

Thereafter, the response signal check module 273 after reset transmits a response request signal to the IP address of the intelligent central platform server again upon reset to check whether or not the response signal is received.

This is to increase the accuracy of the determination of communication disruption through redundant checks, and since there may be cases where communication disruption simply occurs due to an error in the communication unit, a response request signal is transmitted again after reset.

In addition, the continuous operation command signal transmission module 274 determines that the response signal is not received even if the response signal is checked again by the response signal check module after the reset, and determines that it is a communication failure and performs autonomous inspection according to the set scenario after the communication failure point. Continuous operation command information to be continuously performed is transmitted to the accident response means self-checking unit 210, the accident detecting means self-checking unit 220, and the RTU self-checking unit 230.

In this case, the autonomous inspection of the bridge situation response means self-checking unit 210, the bridge detecting means self-checking unit 220, and the RTU self-checking unit 230 is performed according to a predetermined scenario regardless of the communication interruption state.

In the conventional techniques, in addition to the flow of notifying the manager when communication disruption occurs, the system does not perform subsequent operations, thereby causing secondary damage.

However, in the case of the present invention, it is possible to prevent causing secondary damage in advance, so that serious damage to the system can be prevented.

On the other hand, in the present invention, the normal operation state and the operation state from the point of time of communication interruption to the point of resumption are classified and stored, and operation state information from the point of time of communication interruption to the point of resumption is defined as the continuous operation result information.

The continuous operation result storage processing module 275 stores and processes the autonomous inspection result information processed according to the continuous operation command information to the continuous operation result storage module.

The continuous operation result storage module 276 stores the self-check result information provided by the continuous operation result storage processing module 275, and the operation result information is not stored normally, and communication resumes from the point when communication is interrupted. The storage process is dualized so that only the operation result information up to is stored.

Then, the communication recovery check module 277 periodically transmits a response request signal to the IP address of the intelligent central platform server to check whether or not a response signal is received.

Further, the continuous operation result information transmission module 278 transmits the autonomous inspection result information stored in the continuous operation result storage module to the intelligent central platform server when receiving a response signal from the intelligent central platform server.

Therefore, it is possible to prevent information omission by automatically providing information that has been self-checked during a communication unavailable time when communication is resumed.

After that, when the time, season, and weather where the abnormality occurs frequently, the information of the inspection message is displayed on the screen in a pop-up format. For example, in summer/cloudy/11 am, the maintenance message information for the first motor is displayed on the screen in a pop-up format so that the manager checks the first motor.
